Backers of an initiative to end marijuana prohibition in Arizona launched a pair of Mother’s Day-themed billboards in Phoenix and Tucson on Monday. An image of the billboard is attached, and a high-resolution version is available at http://bit.ly/1N3OkrX.

Leaders of the Campaign to Regulate Marijuana Like Alcohol will hold media availabilities at 11 a.m. in front of the billboard in Phoenix (1925 E. Indian School Rd.) and at 2 p.m. in front of the billboard in Tucson (3640 S. 6th Ave.).

The ads, which are targeted at younger voters, feature a young woman sitting with her mother and ask: “Have you talked to your parents about marijuana?” The goal of the ads is to flip the script on marijuana education and encourage younger voters to start conversations about marijuana with their family members — especially older generations who have been led to believe marijuana is more harmful than it actually is. The billboards direct viewers to a website — http://TalkItUpArizona.org — that allows them to send a message about marijuana to their parents or other relatives. The billboards will run through Sunday, which is Mother’s Day.

“For decades, the federal government distributed anti-marijuana propaganda to parents and encouraged them to share it with their children,” said CRMLA Chairman J.P. Holyoak. “It’s time for younger folks to start sharing the facts about marijuana with their parents and other older relatives.

A new study to be published in the Journal of Adolescent Health found that, despite much hand-wringing over concern for kids, marijuana legalization had no effect on teens’ access to the drug in Washington state.

“There was virtually no change in the proportion of teens who reported it was ‘easy’ to access marijuana in 2010 (55 percent), compared to 2014 (54 percent) after the new law was enacted, according to the study,” the American Academy of Pediatrics said in a release.
